Materialize a dataset (Deprecated)

Start a materialization run for a specific dataset. The materialization schedule for the dataset must already exist. **Deprecation notice**: [Datasets](/docs/datasets) are deprecated. Starting June 2, 2026, you will no longer be able to create datasets or edit existing datasets. Migrate your datasets to data models and update any documents that use datasets as a data source to use a different source. See [Migrate a dataset to a data model](/docs/migrate-a-dataset-to-a-data-model). ### Usage notes - Retrieve the **datasetId** by calling the [/v2/datasets](https://help.sigmacomputing.com/reference/list-datasets) endpoint.
